Energy forms are either potential or kinetic. Potential energy comes in forms that are stored including — chemical, gravitational, mechanical, and nuclear. Kinetic energy forms are doing work — like electrical, heat, light, motion, and sound.

Forms of Energy
Form of EnergyDescription
ThermalThe atoms and molecules of a substance possess thermal energy. The more rapid the motion of the atoms and molecules, the greater the total thermal energy.
ElectricalThe form of energy is possessed by charged particles. The charges can transfer energy as they move through as electric circuit.
RadiantRadiant energy travels by means of waves without requiring particles of matter.
Nuclear potentialThe nucleus of every atom has stored energy. This energy can be released by nuclear reactions such as nuclear fission and nuclear fusion.
Gravitational potentialA raised object has stored energy due to its position above some reference level.
KineticEvery moving object has energy of motion, or kinetic energy.
Elastic potentialThis potential energy is stored in objects that are stretched or compressed.
SoundThis form of energy, predicted by vibrations, travels by waves through a material to the receiver.
Chemical potentialAtoms join together in various combinations to form many different kinds of molecules, involving various amounts of energy. In chemical reactions, new molecules are formed and energy is released or absorbed.
